UNITED STATES PATENT OFFICE EMILIO cnnsrr, or cnEsrI-sUn-LnnnA, ITALY, AND MARIUS .PAULOTTO, or PARIS, FRANCE APPARATUS FOR BLEACHING TEXTILE FIBERS WITH A GASEOUS CURRENT SUCH AS OZONIZED AIR Application filed June 15, 1928, Serial No. 285,674, and in France February 2, 1926.

The object of the present invention is to The ozonized air escapes at the other end provide machines and apparatus which are of the tunnel through a passage 160 which particularly suitable for the exposure of runs to an exit flue 161. yarns to gaseous bleaching currents (for ex- The chambers 152 and 153 are provided (Sample, currents of ozonized air) in order to with means to rapidly expel the ozonized air 55 obtain a uniform distribution of the gaseous which leaks from the tunnel into the chamcurrent over all the material to be bleached, bers. For this purpose there is a fan which and which are capable of practical continuous sucks air from the outside and forces it working, simultaneously utilizing all the through two pipes 163 163 which run to gas produced and safeguarding the health the top of the two chambers 152, 153.

The preferred form of the invention is l/Vhen a chamber has to be opened to reillustrated in the accompanying drawings, move or loadatruck, the two regulators 15 1- 5 in which 155 are first shut, and then the fan 162 is set Figs. 1 and 2, respectively, represent an' working.- This fan drives a considerable axial longitudinal section through a vertical quantity of air from outside through 163 plane and a horizontal section of a tunnel 163 into the chamber, this said air itself plant according to the invention; forcing, through pipes 164, the ozonized air 7 Fig. 3 is a transverse section of this plant which has entered from the tunnel into the on the line 3, 3 of Fig. 2; chambers 152-153.

The 175 mounted on a screw we 178, with horizontal axis, which can turn freely on this axis without being able to advance in relation therewith. It is in 1 act, to be noted, in Figs. 7 and 8, that the end 185 of this screw is engaged with a bearing 18.2 by means of a. ball thrust bearing 181.

The other end 183 of the screw 178 rests on a second bearing 184. Bolts 185 connect the two bearings 183, 181 one with the other and act as guides for the sliding carriage 175.

The screw 178 is driven by a shaft 186 through the intermediary of a cone pinion transmission 187, this shaft 186 being itself worked by a crank 188 and a speed reducing mechanism 190.

This device works as follows: The crank 188 is turned thus making the intermediary shaft 186 rotate and consequently the screw 178. This screw is prevented from advancing by the two bearings 182, 184 and therefore causes the carriage 175 to advance, as indicated by the arrow 191, the said *arriage being also prevented from turning by the bolts 185 on which it slides.

The impulse lever 171 is driven by the carriage 175 in the direction of arrow 191; at first it takes up the position shown in full lines in Fig. 5, a position in which this lever engages with the axle 193 of the truck.

The carriage175 moving forwardly draws the truck running on the rails and passes from the chamber 152 into the tunnel 151, pushing back all the set of trucks, and the impulse lever 171 and the carriage 175 then come into the positions shown in broken lines in Fig. 5.

The last truck of the set finally leaves the tunnel 151 running on the inclined plane at the exit from the chamber 153.

This movement can c'asily be obtained by hand owing to'the greatly reduced speed of the transmission mechanism 190.

The carriage 175 can be brought back quickly to its initial position by turning the crank 188 in the opposite direction.

)Ve claim 1.
